Unfortunately, the new log file does not provide more informations... here is what I propose:

run the 20170315 version without gdb, and redirect the output to a log file: photoflow.exe > log.txt, and then send me the log.txt file after the crash

get the latest version I prepared this morning, which is compiled with debugging symbols (that's why the package is twice as big), run it through gdb.exe and send me the backtrace, which this time should show the exact line number at which the crash occurs...

I'm trying to install PF under the last Debian.PPA doesn't work (apt-get update fails).And I'm stuck with the build script at VIPS step (I've got the version 7.x but 8.x is required).Any suggestions ? Thanks !

I have no idea what is happening with the PPA... I will reach the maintainer to see if we can help.

Have you tried with the PhotoFlow/build/build_all.sh script? It should also automatically download and compile the git version of libvips, and compile photoflow against it.The script was exactly meant for compiling photoflow on systems that do not provide a recent enough version of VIPS...

Fail20170316.txt (123.9 KB)But ... that doesn't fail at the same time. The previous scenario the failure occurs during the calculation on the third image. This time it fails just when I open the second one.

The problem is definitely memory allocation... it seems that the program is not able to allocate enough memory for the second or third image:

Saving raw data to buffer...
Raw buffer allocated: 0

There is a pointer to a temporary memory buffer that is NULL, i.e. the memory cannot be allocated.

I think this is due to the fact that my windows executable is 32 bits, but I cannot exclude a memory leak somewhere, as I don't expect the memory allocation to be so large as to hit the limit of 32 bit executables.

Until this is not solved, you will be limited to only one opened image...

Thanks ! That works with LD_LIBRARY_PATH definition (under console).And I can open more than 3 images I've made a try with a photoflow.desktop file for Gnome, but it doesn't like ... is there a way to make it permanent ?What is the path for the PF icon ?
